甘肃省水资源空间匹配分析

Analysis of Spatial Match of Water Resources in Gansu Province

根据水资源空间分布与耕地、农村人口和城镇人口的关系,参照基尼系数的计算方法,建立水资源空间匹配模型。运用该模型对甘肃省水资源进行了实证分析。结果表明,甘肃省的水资源空间匹配程度极差,而且水资源与耕地、农村人口和城镇人口的匹配度均远远超过0.4。据此提出了提升水资源空间匹配度的对策和建议。最后对该模型的进一步应用进行了讨论。

Based on the structure of regional water use and the spatial distributing correlation between arable areas, the rural population, the urban population and the demand of regional water resources, the model was established according to the calculation method for Gini coefficients. A demonstration is applied to Gansu Province. The model is used to make a practical analysis of Gansu Province. The results show that the spatial match of water resources in Gansu Province is quite poor, and the spatial match coefficient/ degree between water resources and arable land, water and the rural population, water and the urban population exceeds 0. 4. Some countermeasures that help improve its spatial matching degree of water resources are offered. Finally, some discussions are carried out concerning further application of the model.
